Bees disappeared.

[Dudex0x]

I had a imperial and industrious bees producing in alvearys and I just checked them and the queens and drones are gone. 

(Edit)

I noticed that part of the alveary was outside my 3x3 chunk loader area (but still inside my claim area). Not sure if this is still an issue with multiblock structures but I am thinking if this wasnt grief it may have been from part of the alvearys unloading when I left the area, breaking the alveary. 

I have since moved the chunkloader so the blocks were all inside the 3x3 area
